GAS BURNER.

Application flcd September .1.5, 1921.

To @it who-'in 'it 72mg/ concern Be it known that I, losnrH' .-i..Mueren, a citizen of the Unit-d States, residing at Cleveland in thecounty of Cuyahoga and .State of hio. have invented certain new anduseful improvements in @as Burners; and l do declare the following to bea full, clear, and exact description the invention, such es will enableothers skilled in the art to which it appertains to make and use thesame.

This invention 'relates to an in'iproved gas burner, and it has for itsprincipal object to generally improve upon devices of this class by theprovision of one of extreme sirnpiicity and durability, which is such inconstruction that it can be manufactured for an extremely low cost, dueto the fact that the parts thereof are in the form of metal castingswhich construction obviates the nccessity of especially machining ordrilling of the parts.

Another object of the invention is to provide a burner which isconstructed of readily disconnectible sections which can be taken apartfor removing carbon and other burnt particles which become lodged insideof the same and in some instances prevent the free 'liow of gas.

i; further object of the invention is to provide a burner which is suchin construction that the already mired gas and air has additional airmixed therewith at the point of ignition? thus insuring an exceptionallyhot flame with a small consumption of gas,

Other objects and advantages of the invention will be apparent duringthe course of the following description ln the accompanying drawingsforming a part of this specification and in which like numerals areemployed to designate like parts throughout the same:

Figure l is a top plan view of the improved burner showing approximatelyonehalf of the upper section of the same broken away to disclose theconstruction of the lower section more clearly.

Figure 2 is a central vertical sectional view through the burner takensubstantially on the plane of the line 2-2 of 1.

Figure 3 is a sectional view taken through the lower section of theburner.

In carrying out the invention, I make use of a lower circular casting orplate l which is formed at its center with an annular de-l pending airand gas inlet 2, being formed Serial No. 500,772.

at closely spaced points around this inlet and around the peripheralportion thereof with a plurality of upstanding upwardly tapered tubularmembers 3. The outer row of tubes 3 are arranged slightly inward of theperiphery of the plate or Casting to provide a flange at. Removablysupported on the lower casting is another casting which is generallydesignated by the numeral 5. rlhis castingincludes a depending annularflange 6 which rests on the aforesaid flange Lland includes a pluralityof closely spaced tubelilre portions 7 which are arranged for co-actionwith the similar parts 3 of the lower casting. it is to be noted thatthe tubular portions of the upper casting are somewhat larger than thecorresponding parts of the remaining casting so that when the burner isin use there is a space formed between the parts 3 and 7 to permitpassage of the gas between these parts for forming substantiallycircular liames over the entire area of the upper side of the burner.The central portion of the upper casting is disposed directly over thefuel intake 2 and the tubular parts 3 of the lower casting are open attheir opposite ends so as to permit additional air to pass upwardlythrough them to mingle with the already mixed air and which passesbetween these parts. and the co-acting parts of the upper casting. Asbefore pointed out, the employment of such an arrangement requires theuse of less gas and at the same time insures an eX- tremely hot flame.Before completing the detailed description, attention is directed to thefact that the arrows A designate the points where additional air issupplied to the already mixed air and gas which escapes through thepassages 8 formed between the parts 8 and 7.

By carefully considering the foregoing description in connection withthe drawings, persons familiar with burners of this class will doubtlessbe able to obtain a clear understanding of the invention. However', abrief review of the operation may well be entered at this point. To thisend, the depending annular part 2 of the lower casting is connected withthe supply pipe and the already mixed fuel is passed through the sameand enters between the two castings and is spread about until forcedoutwardly between the various escape passages 8, and, as aboveindicated, additional air passes upwardly in. the direct-ion of thearrows A.

through the tube-like part 3 on the lower casting and mingles with thealready mixed fuel so as to provide an extremely eHect-ive mixture forformation of :in intensely hot llames.

I claim:

A gas burner comprising` a. lower pletelike casting having e dependingtuel inlet at its center, aplurality ol tapered tube-like extensionswhich are open :at their opposite ends to constitute en* inlet passages'formed on its upper fece, the outermost extensions beingpositionedinward ol tlieperipherel edge or' the casting to provide a flange, andan upper similarly shaped casting formeel ves adepte-fl ten taperedsleeves; seid upper castings being 2o also provided with dependingflange adapted to rest upon the seid flange oi' the lower castings, thebottoni of the suifl tapered sleeves lying1 some (listens-fe above thebuse of the lower Cantine;.whereby fuel passages Aere provided1 lntestimony whereof l here hereunto eet my hand.
